Embodiment Construction
[0022] see Figure 1-2 , a cosmetic cotton die-cutting knife roll 100, comprising a mold roll base 1, a left support shaft 2 and a right support shaft 3, the left support shaft 2 and the right support shaft 3 are respectively arranged on the left and right sides of the die roll base 1; The mold roll base 1 is provided with a plurality of blades 4, and the blades 4 are circular. The blade body 4 includes a base layer 41 , a transition layer 42 and a cladding layer 43 sequentially connected from inside to outside, and the cladding layer 43 forms a blade. The left and right ends of the mold roll base 1 are respectively provided with a protective ring 5 , and the top of the protective ring 5 is higher than the top of the blade body 4 . The diameter of the mold roll base 1 is Φ100mm˜Φ200mm.

Abstract
The invention provides a facial puff die cutting knife edge laser cladding near-net forming control method. A laser cladding technology and a synchronous powder feeding mode are adopted, protective gas and powder feeding gas are both inert gases, according to the technological parameters, the laser power is 800-2500 W, the scanning speed is 3-12 mm / s, the gas flow is 600-2000 L / h, the defocusing distance is 1-12 mm, and the overlap rate is 10-50%. Through the facial puff die cutting knife edge laser cladding near-net forming control method, knife edge near-net forming is achieved, the formingprecision of curved surface substrate cladding stacking pieces is improved, the follow-up finish machining amount is decreased, accordingly, the workload is greatly reduced, the production efficiencyis improved, and the production cost is effectively controlled.
Description
【Technical field】 [0001] The invention specifically relates to a method for controlling a near-net shape of a cosmetic cotton die-cutting blade by laser cladding. 【Background technique】 [0002] As a traditional and classic manufacturing technology, die-cutting technology has been widely used in more than a dozen industries such as printing, packaging, mobile phone digital accessories, health and medical supplies, and electronic labels. Because the traditional flat die-cutting equipment has a series of problems such as poor safety, low degree of automation, and high energy consumption, it is being eliminated by the market, so the market for rotary die-cutting equipment has expanded rapidly. [0003] The core component of the rotary die-cutting equipment is the die-cutting tool holder, which is composed of a die roller, a round roller and a die frame. Wherein the die roller body is manufactured with a knife edge according to the shape of the processed product. The mold roll...
